Title: Improvements in or relating to radio tuning apparatus
IPC: H03J5/18
Filed: 1944-10-24
Abstract: 602,457. Push-button tuning mechanism. CRAMER, S. S. Oct. 24, 1944, No. 20615. Convention date, Dec. 30, 1943. [Class 40 (i)] A preset tuning device has means for moving a tuning member, first to one extreme position and then towards the other, means being provided to stop the member on the return, when it reaches a predetermined position. Figs. 1, 5 and 8 show'one arrangement, in which energization of an electromagnet 10 (Fig. 8), oonnected in series with electromagnet 46 and a selected one of the group of electromagnets 41 causes an armature 8 connected to the capacitor rotor to -rotate against spring 13 (Fig. 1). On reaching the " all out " position, the rotor plates depress an arm 53 (Fig. 8), cutting out electromagnet 10, so that the armature is rotated by the spring in the opposite direction. A locking device, including electromagnet 46 is provided to prevent the return of member 53 until the circuit is de-energized. The energization of one of electromagnets 41 causes an associated pivotally mounted member 32 (Fig. 5) to be pulled into the path of a pin mounted on shaft 19 which is connected through gearing to the capacitor rotor, so that the rotor is stopped in a position dependent on the setting of member 32, which is determined by a setting screw 28. In a modification (Fig. 9, not shown), a member carried by the armature cuts out the driving electromagnet 10 by striking a contact actuating member, which also locks itself in position by causing a current to flow through a winding of which it forms the core. The set may be muted during tuning by grounding the aerial, shorting the speaker, or cutting off the receiver supply. Indication that tuning has been effected may be given by lighting lamps mounted behind translucent push-buttons. Specification 600,717, [Group XXXV], is referred to.

Title: Generator for producing control impulses for striking the controllable rectifiers of a three-phase d.c./a.c. inverter
IPC: H02M1/08
Filed: 1969-04-23
Abstract: 1,269,361. Magnetic storage arrangements. DANFOSS A.S. 23 April, 1969 [26 April, 1968], No. 20735/69. Heading H3B. [Also in Division H2] A shift register for use in the control of rectifiers in a static inverter (see Division H2) has six bi-stable stages which emit control signals S1 to S6 to respective rectifiers when in the " 1 " condition and when in the " 0 " condition these signals are suppressed, and comprises multihole magnetic storage cores arranged in a known manner as illustrated in Fig. 5. Each stage has a main storage core 111, 121, 131, 141, 151, 161 and-except for the last stage-an intermediate core 112, 122, 132, 142, 152. A further feedback inverter core 181 is also provided. Each core has holes b, c, d and a centre hole a. Coupling loops e, f are passed through the output hole c of a preceding core and input hole b of the next succeeding core. Each main storage core has a signal output conductor g through its hole d. A conductor 23 which carries shift impulses B1 passes through holes a of the main storage cores. A conductor 24 which carries shift signals B2 is passed through the holes a of the intermediate cores and through hole a of core 181. Conductors 23, 24 are connected at their ends to a conductor 25 through which are passed holding impulses H which prevent feedback from the intermediate core to the main core of each stage. A conductor 26 runs through the holes c of all the cores and carries transmission impulses I which occur before each of the shift impulses B1, B2. A return loop 171 passes through input hole b of the 1st main core 111 and through output holes d of cores 132 and 181. In operation, assuming main core 111 energized and in condition " 1 ", an impulse I causes demagnetization of hole c zone. Upon occurrence of shift impulse B1 core 111 is blocked and core 112 becomes magnetized via loop e. The main core 111 is now in " 0 " condition and core 112 in " 1 " condition. When an impulse B2 is sent following a further impulse I the condition of the intermediate core 112 is transferred to the next main core 121. Thus the contents of each main core is transferred in two steps to the next main core. The feedback inverter core 181 is energized by each impulse B1 and is blocked again by each shift impulse B2. Consequently an impulse which energizes the main core 111 is sent via conductor 171, only when the third intermediate core 132 has reached its " 0 " condition. The inverter core thus provides for the first three stages outputs assuming a " 1 " condition with the first three shifts (111000) when all the stages have been set to " 0 " prior to commencement of operations. This group of three is shifted along the register and is followed by a group of three " 0 " conditions and so on.

Title: Improvements in or relating to semiconductive devices
IPC: H01L29/40
Filed: 1960-06-14
Abstract: 875,674. Semi-conductor devices. WESTERN ELECTRIC CO. Inc. June 14, 1960 [June 17, 1959], No. 20835/60. Class 37. A semi-conductor device comprises a semiconductor body having five layers, the first, third and fourth layers being of one conductivity type and the second and fifth layers being of opposite conductivity type; the fourth layer is of relatively high resistivity while the remaining layers are of relatively low resistivity. The embodiments shown comprise silicon PNPN switching diodes of the type disclosed in Specification 813,862, with the addition of a 7T-type (i.e. weakly doped P- type) layer in front of the final N-type layer; moreover, the NP junction has a small area relative to the #N junction. This arrangement is said to reduce the likelihood of dynamic breakdown, i.e. breakdown in response to a steep voltage pulse of amplitude below the design breakdown voltage due to the current associated with the capacitance of the reverse biased NP junction. The Fig. 1 embodiment may be made by a succession of vapour-solid diffusion steps; e.g. a #-type silicon wafer has one surface subjected to three successive diffusions to form relatively thin layers 11, 12, 13 and relatively thick layer 15 is formed by diffusion into the other surface. Layers 11, 12, 13 are then partially etched away to form the mesa shown. In Fig. 2 to produce P-type layer 23, the first diffusion is limited by masking to the portion shown by the broken line. In Fig. 3, the limited area P-type layers are on opposite sides of a median line through the device. In Fig. 4, a shorting electrode 46 is employed to enhance control of the turn-on current. The addition of a control electrode to the intermediate N- or P-type layer in Fig. 1, 2 or 3 produces a controlled rectifier. The invention is applicable to PNPN germanium diodes, the intermediate N-type region being of increased thickness, and to NPNP wafers, in which case the additional high resistivity layer is of weakly doped N-type.

Abstract: The invention comprises diperfluoroacylamides of the formula: <FORM:0767089/IV(b)/1> where Rf and R1f are perfluoroalkyl groups of 1-11 C atoms, and a method of preparing them by the action of a sodium salt of a fluorocarbon monocarboxylic acid on PNCl2 (phosphorus dichloronitride) in the presence of butyl benzene which serves to provide the hydrogen of the product; also by the action of primary fluorocarbon amides on anhydrides.  In examples, phosphorus dichloronitride is caused to react with sodium heptafluorobutyrate in butyl benzene to give the amide (nC3F7CO)2NH; trifluoroacetamide reacts with trifluoracetic anhydride to give the amide (CF3CO)2NH; perfluorodecanoic amide and perfluorodecanoic anhydride react to give the amide (nC9F19CO)2NH; perfluorobutyric anhydride and amide give the corresponding product.  The compounds are surface-active, the best containing 3-11 carbons.  When the amide in the above reaction is of an acid differing from the anhydride, the products contain different groups Rf and R1f; the equation being: <FORM:0767089/IV(b)/2> + <FORM:0767089/IV(b)/3> --> <FORM:0767089/IV(b)/4> + <FORM:0767089/IV(b)/5> Specification 767,088 is referred to.

Abstract: 386,681. Cartons, boxes, &c. BARTON C. N., 12, Cromwell Grove, London. July 22, 1931, Nos. 20974 and 21812. [Class 18.] In a collapsable carton, box, &c. for eggs, &c., the whole or part of a filler or like compartment forming device is maintained in interengagement with the carton both in its collapsed and erected conditions, and a part or parts of the filler are movably secured to the carton in such a way that, when the device is collapsed, the part or parts may be turned to lie substantially parallel to the plane of the unfolded blank forming the carton and within the area of the blank. In the embodiment shown, the base 1 of the carton carries extensions along all four sides, which extensions can be turned up so that extensions 5, 6 form the ends of the carton and extensions 2, 3 form reinforcements to the front and back sides. The extensions 5, 6 carry further flaps which interlock by means of tongues and slots to form the front 8 and back 7 ; and extension 3 carries a further extension which forms the lid 4. The filler comprises one or two strips 11 formed with hook-like lugs which project through curved slots in the ends 5, 6 so that when the ends and sides of the carton are let down, the filler also assumes a flat, horizontal position. If two slots intersecting at right angles, with curved intersecting parts, are provided in the ends of the carton, the filler strips will pass right through the slots. A flap 14 attached to the lid by a tongue and slot connection enters the hexagonal space in the filler when the lid is turned down, and the carton is thus formed with six compartments. Twelve compartments can be formed by providing two fillers similar to the above separated by a partition, or by forming two hexagonal cells in the strips 11 and separating them by a cross strip, and by providing two corresponding flaps 14 connected to the lid. A carton with three compartments is formed by threading a strip through slits near the centre of one side and directing the ends of the strip towards the opposite corners. More than one filler may be employed and the flap 14 may be carried by any convenient part of the carton.
